    This man is a hero. What he didn’t explain in this briefing was he was DEMOTED to a scheduling position. When the chairman found out, he had every executive fired. Watch the documentary CHALLENGER: A rush to launch. It is amazing that BOTH tragedies were made by unethical executives. We lost 14 souls on a challenger and Columbia. That’s loss of human life. You can never put a price tag on that. God bless this unsung hero and a man named Roger Bojilea. This is the type of ethics and case stories that need to be taught to our children earlier on so they truly understand what ethics mean and how important they truly are.

    Thank you sir, and also thanks to Roger Bosjoly, the original whistle-blower. He was a guest speaker in an engineering ethics course I took at Purdue University while studying structural engineering about 25 years ago. He said that the decision NOT to launch amongst the engineers was UNAMINOUS. As a reward for his honesty, his career was destroyed, he was blacklisted, and eventually became an independent consultant.

      I'm an engineer and have been in that same situation. There is often pressure, either scheduling, financial and/or political, which can affect some people's decision making. Managers often will succumb to that type of pressure while engineers are usually more data-driven. It's called cognitive dissonance. Emotions and beliefs can sometimes conflict with and override logic and reason. This conflict can cause psychological stress and lead to flawed decision making.

      His last sentences were, "Make sure that what you thought was important got to the right people. That's what I wished I would have done." Refusing to sign off on that launch didn't save anybody. He didn't actively promote the launch, but he didn't actively stop it either, which he could have done, and that tormented him. He stepped aside and left it to others.
      He was one of the good guys, absolutely, but had he done more, he could have saved the day, all on his own. The launch would have been scrubbed, he would have been fired, and no one would have died. That would have made him a hero, but nobody, not even he himself, would ever have known that he had saved seven lives and the most sophisticated and expensive spacecraft in human history. We can never know who the heroes are. We can only know whether we ourselves are working toward goodness, as Boisjoly would say.

      I worked on the SRB parachute recovery system (SRBDSS). Our system had nothing to do with the failure, and as a matter of fact, the drogue parachute which was seen coming down with the isogrid structure, and was recovered in condition to have been reused, which of course they didn't!
      We were only concerned with the performance of our system, above the forward deck attachment to the SRB's, and so never looked at the downstage postflight reports, even though it was in the same document. We were called in to submit a complete analysis of everything about our subsystem. At the time, I finally looked at the downstage reports for previous flights, and found the the previous August and the April before that, there was leakage past the O-rings for 120 degrees (1/3 of the circumference of the booster) on both flights! Fortunately, the leaks didn't cause any harm..then. But they were there! Had I know this and said anything, I would have been told to mind my own business, as the booster below the parachute attach points were not our responsibility! In his book, Mr. McDonald states that Larry Malloy told MT engineering to "Stop thinking like an engineer and start thinking like a manager!" Wonder if LM has ever had a decent night's sleep since?

      Anyone who is going to be a manager of engineeners on projects where lives are at stake certainly should be humble and level headed enough to follow the protocol that engineers set in place, like "Don't launch unless temps are within the recommended guideline." Following guidelines set in place shouldn't be that hard. The bozos here with big egos apparently were unable to reel those egos in and say "it's a no go". Apparently "just saying no" is more complicated than rocket science.

      904 CZV That’s certainly true but there’s many other parts of the story to consider. NASA was only allowed to study, improve or redesign those parts of the shuttle that had the biggest problems. Main engine turbo pumps, some of the thermal protection as an example. And they only got those things funded because of promised future cost savings and higher payload to orbit. After about 1992 they weren’t allowed to make upgrades hardly at all. That led to their management having to invent rationals to keep flying with dangerous problems.

    This made me think about this gentleman’s career. To level up to the rank he was in importance to the SRB system and then have your career highlighted by the Challenger disaster. The good guys don’t always finish first even when the evidence points in that direction. I hope people can view his career as more than the Challenger incident and see that he attempted to stop the launch but red tape prevailed.

    My dad was a aeronautical space engineer for NASA he built the cooling system on the space shuttles I grew up in Houston Texas dad worked at Johnson Space Center in Clear Lake I was fortunate enough to be able to work there for a while with the astronauts we take them down in the water in the pool and get them neutral in case they need to go outside the cargo bay for any missions I feel God was stopping the Challenger by so many delays and people forced it to happen unfortunately some very tragic consequences only saw my dad cry once in his life and that was the time

Even though it may not have been enough to save the crew's lives, in a way it saved his own life and he was able to live his life without guilt.

    I READ HIS BOOK (TEXT) & he was SPOT ON. NASA & the company he was employed with, at time tried to stir him away from those officials who later assembled the Investigation Committee of the cause of the loss of crew, of Challenger. Before NASA & his management he worked with, tried to prevent him from speaking with the organizers, didn't happen. Many recognized him & asked his engineering views & later testified in front of the Investigation Committee on the loss of Crew of Challenger. I don't remember the name of his text but is available from bookstores. Later, he was in charge of re-designing the joint area..Since then no failures have occurred

If indeed your fabrication fails in a minor way, or a major way, chances are you know why & how.

All my life I was taught to be honest and straight forth, and to hear about this account that killed two crews of two shuttle missions ... I just don't know how to react. It's beyond outrage. And of all programs to do this, NASA, with the most dangerous missions. What a huge shame.
